Type Fund Benchmark Net
The fund itself has not been rated by an independent rating agency. Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by BlackRock and takes the median rating of the three agencies when all three agencies rate a security the lower of the two ratings if only two agencies rate a security and one rating if that is all that is provided. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.

Negative weightings may result from specific circumstances (including timing differences between trade and settle dates of securities purchased by the funds) and/or the use of certain financial instruments, including derivatives, which may be used to gain or reduce market exposure and/or risk management. Certain transactions the funds may utilize may give rise to a form of leverage through either (a) additional market exposure or (b) borrowing capital in an attempt to increase investment return. The use of such transactions includes certain leverage-related risks, including potential for higher volatility, greater decline of the fund’s net asset value and fluctuations of dividends and distributions paid by the fund.

Allocations are subject to change.
